Blueberries have many health benefits, including the highest antioxidant ability of all fresh fruit. They also have effective anti-inflammatory, anti-blood clotting and antibacterial effects. In the past they were often used to combat diarrhoea and food poisoning. They are also thought to have anti-ageing properties.

Blueberries are not sour and can be eaten raw, so preserving their vitamin C content. Lightly cooked fruit retain their therapeutic properties.
